HistoryA character grade: shown, never part of Galesburg’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Galesburg’s 357 sits above most of its state (98% of Illinois towns have fewer) while its 1,051 historic buildings outnumber those of 99% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share is a Census survey estimate (±3.1 points). The founding year is the first post office, not a stated founding date.

Galesburg was founded by George Washington Gale, a Presbyterian minister from New York state who had formulated the concept of the manual labor college and first implemented it at the Oneida Institute near Utica, New York. In 1836 Gale publicized a subscription- and land purchase-based plan to found manual labor colleges in the Mississippi River valley. Land was purchased for this purpose in Knox County and in 1837 the first subscribers to the college-founding plan arrived and began to settle what became Galesburg.
